Rosa plant named &#39;FARROWRSP&#39;

ABSTRACT

A new and distinct  Rosa  cultivar, for garden use named ‘FARROWRSP’ is disclosed, characterized by bright salmon and yellow colored flowers. Plants are distinctively compact and useful for small garden spaces and have an above average resistance to diseases. The new variety is a  Rosa , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Rosa hybrida.

Variety denomination: ‘FARROWRSP’.

BACKGROUND OF THE INVENTION

The new Rosa cultivar is a product of a chance discovery by the inventor, Christopher Michael Farrow. The discovery was made during 2010 at a commercial nursery in Maryland. The new variety is the result of a naturally occurring branch mutation of Rosa ‘ChewMayTime’, U.S. Plant Pat. No. 18,347.

Asexual reproduction of the new cultivar was performed by softwood cuttings at a the same commercial nursery in Warwick, Md. during 2010. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘FARROWRSP’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘FARROWRSP’ These characteristics in combination distinguish ‘FARROWRSP’ as a new and distinct Rosa cultivar:

1. Bright salmon and yellow colored flowers. 2. Strong disease resistance. 3. Very compact plant habit. 4. Very good landscape performance in tight or small spaces.

Plants of the new cultivar ‘FARROWRSP’ are similar to plants of the parent in most horticultural characteristics, however, plants of the new cultivar ‘FARROWRSP’ differ in the following:

1. Flower color of the new variety is salmon, flower color of the parent is orange.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘FARROWRSP’ can be compared to the commercial variety Rosa ‘ChewperAdventure’, unpatented. These varieties are similar in most horticultural characteristics; however ‘FARROWRSP’ differs in the following:

1. Flower color is salmon. Comparator flower is pink and orange. 2. The new variety has a single whorl of petals, compared to the semi-double whorl of this comparator.

Plants of the new cultivar ‘FARROWRSP’ can also be compared to the commercial variety Rosa ‘Chewpatout’, unpatented, Ser. No. 14/757,061. These varieties are similar in most horticultural characteristics, including disease resistance and flower shape. However ‘FARROWRSP’ differs in the following:

1. Flower color is salmon. Comparator flower is red.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a plant of ‘FARROWRSP’, growing in the ground in Michigan.

FIG. 2 illustrates a typical 2 year old plant of the new variety, in a 2 gallon pot. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION
